Abstract

The invention concerns a length adjustable telescopic pin support. The telescopic pin support fixes for example a concrete drilling machine between floor and ceiling at a place of work. When you have adjusted the telescope and found the right level the screw mechanism is placed up in the ceiling and you need to stand on a stool or such like to reach the screw mechanism. The invention is solving this problem owing to the fact that the pin is working as both pin and screw mechanism. The pin is equipped with both a screw (7) and a carried in a bearing grasp (8), whose grasp-slits (9) get a three-side range of the perforated hole edge (10) of the inner support (2). In this way a pin support with the safe grasp of the pin is received and the screw is placed in a comfortable place. The invention is used mostly at fixing of concrete drilling machines on building-places of work.

Description

_501 813 2 Fig 1 visar ett teleskopiskt sprintstöd sett framifrån. _501 813 2 Fig. 1 shows a telescopic sprint support seen from the front.

Det teleskopiska sprintstödet består av ett ytterrör 1 och ett i detta infört innerrör 2 som teleskopsliknande är inställbart. Innerröret 2 har i sin övre ända en hylsa 3 monterad vars ytterdimension överenstämmer med ytterrörets 1 ytterdimension, detta för att sprintstödet skall kunna vändas upp och ner i maskinfixtur, som ej visas.The telescopic sprint support consists of an outer tube 1 and an inner tube 2 inserted therein which is telescopically adjustable. The inner tube 2 has at its upper end a sleeve 3 mounted, the outer dimension of which corresponds to the outer dimension of the outer tube 1, so that the pin support can be turned upside down in a machine fixture, which is not shown.

På ytterröret 1 är ledhuvud 4 fast monterat. Vid ledhuvud 4 är en ledad mutter 5 lagrad och fjäderupphängd med fjäder 6. I ledad mutter 5 skruvas en manuellt och med verktyg, som ej visas, hanterbar förskruvning 7 vars topp är försedd med lagrat grepp 8. Grepp 8 griper tag i innerrörets 2 perforerade hålkant 10 och genom att skruva på förskruvning 7 trycks innerröret 2 uppåt.On the outer tube 1, hinge head 4 is fixedly mounted. At articulated head 4, an articulated nut 5 is mounted and spring suspended with spring 6. In articulated nut 5 a manually screwable screwdriver 7 is screwed with tools, not shown, the top of which is provided with stored grip 8. Grip 8 grips the perforated inner tube 2 hole edge 10 and by screwing on screw connection 7, the inner tube 2 is pushed upwards.

På grepp 8 finns en greppslits 9 vars sidor greppar tag i innerrörets 2 hålkanter 10 åtkomliga sidor vilket gör att ofrivillig släppning av grepp 8 är omöjlig under belastning dessutom måste innerröret 2 lyftas en aning innan man kan frigöra greppet 8 genom att trycka på den fjäderupphängda förskruvningen 7 .On grip 8 there is a grip slot 9 whose sides grip the hollow edges 10 of the inner tube 2, which makes accessible sides which makes involuntary release of grip 8 impossible under load. In addition, the inner tube 2 must be lifted slightly before the grip 8 can be released by pressing the spring-loaded fitting 7.

Greppet 8 parallellstyrs med innerröret 2 genom att greppet är utformat som en bygel med bygelskänklar 11 .The grip 8 is controlled in parallel with the inner tube 2 in that the grip is designed as a stirrup with stirrup legs 11.

För att bekvämt kunna skruva på förskruvning 7 är denna försedd med handvred 12 och spärrnyckeltag 13.In order to be able to comfortably screw on screw connection 7, this is provided with a hand knob 12 and a locking key holder 13.
